To all whom it may concern Be it known that I, HENREYHARDON H UNT, of San Antonio, in the county of Bexar and State of Texas, have invented a new and Im- 5 proved Compound for Making Brick, Tile, &c.; and I do hereby declare that the following is a full, clear, and exact description of the same. My invention relates to a novel composition for making brick, tile, and analogous material; 10 and it consists in combining h draulic cement with a soft stone known as ma nesian limestone which is found in great abundance in i. W esfern Texas, and which has heretofore been considered a waste material.

15 In preparing the compound I take threefourths of a pound ot hy drau lic cement and 5 mix with it three and one-half pounds of the soft stonewellgrg nd up, These materials are i g 2J2 Examiner dampened and put in molds and pressed. They 20 i re nex a en out ot' i'ir'ss and allowed to dry for one day, after which they are set in water and kept there for forty-eight hours. 'The brick or tile, as the case may be, are then taken out and are ready for use.

Having thus described my invention, what I claim as new is- A compound for making brick, tile, &c., composed of hydraulic cement and the pulverized stone described, combined in the manner and about the proportions set forth.
